Timothy and Nancy Kahanek, individually and on behalf of their daughter Kyn-dil’s estate, sued Dr. Sheldon Gross, alleging that drug treatment prescribed by Dr. Gross caused Kyndil’s death. Dr. Gross moved for summary judgment in part on grounds thаt their claims were barred by the two-year limitations period of Texas Revised Civil Statute article 4590i, § 10.01. The trial court granted the motion. The court of appeals reversed and rеmanded, holding that limitations had not yet run. It concluded that Dr. Gross maintained a continuing course of treatment for Kyndil that ended the day she stopped taking Tegretol, and that Kyndil stoppеd taking the drug at the time of her death less than two years before suit was filed.
Kyndil Kahanek was born in 1986 with a congenital heart defect, and subsequently underwent successful heart surgery. In 1990 she suffered a seizure. Kyndil was referred to Dr. Sheldon Gross, a pediatric neurologist in San Antonio. Dr. Gross prescribed the medication Tegretol to control the seizures. The next month the Kahaneks took Kyndil back to Dr. Gross for a follow-up visit. After obtaining tests to determine Kyndil’s blood count and Tegretol level, Dr. Gross advised the Ka-haneks to continue giving her Tegretol.
On January 20, 1992, the Kahaneks again took Kyndil to Dr. Gross, rеporting that she had suffered another seizure. Dr. Gross increased the Tegretol dosage and requested that Dr. Gordon Barth, Kyndil’s family physician in Yorktown, conduct a Tegretol-level test. Dr. Gross did not examine Kyndil again, although he last ordered a refill of her Tegretol prescription on August 10, 1992. Dr. Barth began authorizing refills of the medication in September 1992, and Kyndil continued to takе Tegretol. On June 12, 1993, Kyndil complained of nausea and abdominal pain. *520 The Kahaneks took her to Santa Rosa Children’s Hospital, where she died the next day after her liver and heаrt stopped functioning. Tegretol poisoning allegedly contributed to her death.
On June 13,1995, the Kahaneks brought wrongful death and survival actions against Dr. Gross. The Kahaneks alleged that Dr. Gross was negligent and grossly negligent in failing to diagnose the severity of Kyndil’s condition, failing to prescribe appropriate medication, failing to recommend an appropriate level of Tegretol, failing to monitor Kyndil properly while she was taking Tegretol, and failing to warn the Kahaneks of the risks associated with Tegretol. Dr. Gross moved for summary judgment, based in part on the Medical Liability and Insurance Improvement Act’s two-year statute of limitations. The trial court granted summary judgment for Dr. Gross, and the Kahaneks appealed.
The court of appeals reversed the summary judgment and remanded the case to the trial court.
A defendant moving for summary judgment on the affirmative defense of limitations bears the burden of conclusively establishing that defense.
See Jennings v. Burgess,
Dr. Gross argues that his treatment of Kyndil ended in January 1992 and was not extended by the later refills of the Tegretol prescription. Thus, he urges that
Rowntree v. Hunsucker,
In contrast, thе Kahaneks allege that Kyndil’s death resulted from her taking the prescribed Tegretol. The Kaha-neks further allege, and presented some supporting evidence, that Dr. Gross had a duty to monitor Kyndil more closely while she was taking Tegretol; Dr. Gross does not dispute that he maintained a duty to monitor her while she was taking the medication. Thus, this is not a suit in which Kyndil, or her parents, werе entrusted to self-administer a medication. Rather, this case involves allegations that a physician was required to monitor the effects of a medication while it was being taken, and that the failure to do so contributed to the patient’s death. In
Rowntree,
we recognized this difference: “There are some situations in which the statute would run from the date of the last drug treatment, if the course of that treatment is the direct cause of the injury.”
In determining when a course of drug treatment ends, we consider such factors as: (1) whether the physician continues to examine or attend the patient, and (2) whether the condition requires further services from the physician. See id. at 106. The parties do not dispute that Dr. Gross last examined Kyndil on January 20, 1992. Nor do they disagreе that he refilled the Tegretol prescription until August 10, 1992. As the Kahaneks presented evidence to suggest that a physician who prescribes Tegretol must continually monitor the patient’s blood Tegretol levels, Dr. Gross maintained a continuing course of treatment for Kyndil so long as he was prescribing Tegretol for her. Beginning in September 1992, still more than two years beforе the Kahaneks filed suit, Dr. Barth prescribed Kyndil’s Tegretol and authorized her refills. Because Dr. Gross was no longer authorizing refills of Kyn-dil’s Tegretol prescription as of September 1992, and was thеrefore no longer responsible for monitoring her blood Tegretol levels, Dr. Gross’s course of treatment with Kyndil ended in September 1992.
Limitations on a wrongful death claim based on negligеnt health care is not tolled or extended because the decedent is a minor.
Baptist Mem’l Hosp. Sys. v. Arredondo,
The Kahaneks’ survival claim, however, is not barred. That action is the same action Kyndil had the day she died and is wholly derivative of Kyndil’s rights; thе injury is hers, and the damages are those she suffered while alive.
See
Tex. Civ. Prac.
&
Rem.Code § 71.021;
Brown v. Shwarts,
Accordingly, the Court grants Dr. Gross’s petition for review, and without hearing oral argument, see Tex.R.App. P. 59.1, affirms thе court of appeals’ judgment on the survival claim, reverses the court of appeals’ judgment on the wrongful death claim, and renders judgment that the Kahaneks take nothing on their wrongful death claim.
